Abstract (en)
Rotary sieve drum unit (14a; 14b) comprising sieving openings (42a; 42b) arranged around a centre point of the sieving openings (42a; 42b) and being categorized in at least one first structure group (44a, 44a', 44a"; 44b, 44b') and at least one further structure group (46a, 46a'; 46b, 46b'), wherein in the first and second structure group the centre points of neighbouring sieving openings are arranged at a first (48a; 48b), respectively a second (50a; 50b) intra-distance to one another. A smallest structure distance (52a; 52b) between a centre point of at least one sieving opening (42a; 42b) in the at least one first structure group (44a, 44a', 44a"; 44b, 44b') and a nearest-situated centre point of at least one sieving opening (42a; 42b) in the at least one further structure group (46a, 46a'; 46b, 46b') is greater than the first intra-distance (48a; 48b).
